Test conditions and notes5
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on http://www.meanwell.com)
  5. 5. Derating may be needed under low input voltages. Please check the derating curve for more details.

FAQ

Can I use the SP-320-48 for 48V telecom or networking equipment?

Yes, if the equipment is designed for 48V DC input and the total load stays within 320W and 6.7A. That makes it relevant for 48V communications, networking, and industrial electronics that need a regulated DC source.

Is the SP-320-48 suitable for a 48V industrial control system?

It can be used for 48V control hardware where the full connected demand does not exceed 320W or 6.7A. Its constant voltage output is intended for equipment that requires a fixed 48V DC supply.

Would this model work for 48V automation or embedded devices with moderate current demand?

Yes, provided the devices require 48V DC and the combined load remains at or below 320W and 6.7A. It fits applications where voltage is higher but current demand is lower than comparable 12V or 24V systems.

Can the SP-320-48 power several 48V loads from one supply?

It can, as long as the total output requirement across all connected 48V devices stays within 320W and 6.7A. That makes it practical for shared 48V DC distribution in control or communications environments.

Is the SP-320-48 intended for outdoor use?

The operating temperature range is specified as -20°C to +65°C, but no IP rating is provided in the available specs. Based on that information, temperature capability is known, while direct outdoor exposure suitability is not confirmed.

How does the SP-320-48 compare with the other SP-320 variants?

The listed SP-320 models include SP-320-12 at 300W, 12V, 25A; SP-320-27 at 315.9W, 27V, 11.7A; SP-320-36 at 316.8W, 36V, 8.8A; and SP-320-48 at 321.6W, 48V, 6.7A. They are in the same power class, with the differences centered on output voltage and resulting current capacity.
